Specification of Letters Patent."

Patented Aug. 15, 1916.

Application filed August 14, 1914. Serial No. 856,714.

To all whom it may concern.-

Be it known that I, GEORGE W. BUMGAR- NER, a citizen of the UnitedStates, and resident of Baltimore, Maryland, have invented certainImprovements in Non-Freezing Water-Closets, of which the following is aspecification.

In the description of the said invention which follows, reference ismade to the accompanying drawings forming a part hereof, and in whichFigure 1 is a central sectional view of such parts of the improvedcloset as are involved in the present invention; and Fig. 2 a plan ofthe same. Fig. 3 is a View illustrating an alternate construction ofparts of the apparatus.

Referring now to Figs. 1 and 2 of the drawings, 1 is a part of the bowlof the closet, and 2 a shell having a branch 3 which connects it to thebowl.

4 is a pipe leading from the shell 2 to the flushing tank which, as itforms no part of the present invention, is not shown.

6 is the main water supply pipe extending downward from the shell 2, tothe valve chamber 7 the bottom of which is adapted for attachment to theservice water pipe not shown.

A portion of the valve chamber 7 is accurately bored to produce thecylinder a, and is provided with a by-pass 10.

Between the openings 6 which connect the by-pass 10 with the interior ofthe cylinder a, is a piston 12, and extending from the lower end of thepiston and integral therewith, is a stem 13 the part d of which issquare in cross-section. The remaining part 6, of the stem 13 may becylindrical, and to its end is secured the conical valve 14 which isformed of vulcanized fiber.

The seat 15 for the valve 14 is formed at the lower end of a squaresleeve 16 and is screwed into the valve chamber. The interior of thesleeve 16 is considerably larger than the part c of the stem, in orderthat water can pass around it from the service pipe, not shown, to theby-pass when the valve 14 is open or in its lowest position as shown inFig. 1 of the drawings. The sleeve 16 which surrounds the stem as beforestated, is square, and should the piston 12 be turned by means of therod 17, the sleeve also will be turned and its threaded end screwed intothe valve chamber, or unscrewed from it; and in the latter case,

admit of the piston and the conical valve 14 being withdrawn from thechamber.

It will be understood that, due to the part cl of the stem 13 beingpolygonal and loose within the sleeve as described, that in turning thepiston to screw or unscrew the seat 15 in the valve chamber 7, thevertical position of the piston is not changed.

Ports 9 provide for the passage of water from the sleeve 13 to theby-pass 10 and to both ends of the piston 12 which are thereforesubjected to a common water pressure.

17 is a rod screwed tightly into the piston 12 and extending upwardthrough a suitable packing box 19 at the top of the shell 2.

20 is a valve fastened to the rod 17, which when the valve 14 isunseated bears tightly on the seat 22.

24 is a branched rocker pivoted at h to a lug 27 formed as a part of theshell 2. One end of the rocker serves as the support for the closet seat30, and the other end carries the weights 32 which overbalance the seatwhen the same is unoccupied. The rocker is also provided with inwardlyextending pins 33 which as the seat is depressed bear upon the disk 34and force the rod 17 and the parts connected thereto to their lowestposition as shown in Fig. 1, when water from the service pipe passes tothe closed flushing tank before referred to.

When the seat is released the pressure of water acting on the valve 14,closes the said valve, and opens the valve 22 thereby admitting waterfrom the flushing tank to the bowl 1, and the flushing operationcontinues until the tank is practically empty, and the said tank is notfilled until the seat is again occupied for a period.

To insure the upward movement of the rod 17 and its atachments,independently of the water pressure, the underside of the branchedrocker is provided with the arms 35 which as the seat rises bear againstthe underside of the disk 34 and thereby cause its elevation.

37 is a small aperture in a nozzle projecting from the valve chamber 7,which is uncovered when the piston 12 is in its highest position. Itsfunction is to drain the cylinder below the piston of its containedwater and thereby-insure the operation of the apparatus in freezingweather.

In Fig. 3 the apparatus corresponds with that above described, exceptthat a coiled spring 39 one end of which bears against the underside ofthe disk 3% and its other end passes through a hole in the lug 27 issubstituted for the weights 32.

I claim as my invention 1- 1. In a water closet apparatus, a bowl, ashell which is open to the bowl and provided with a nozzle leading to aflushing tank, an annular valve seat and a valve therefor in the shellsituated above the said nozzle, a valve chamber adapted for theadmission thereto of service water, the same having a drain aperture; anannular detachable service water valve seat which is screwed into thevalve chamber, the same being provided with an upwardly extending sleeveof poly onal cross-section, a piston in the chamber to control the drainaperture, and an upwardly closing service water valve having astem whichconnects it with the piston, the portion of the said stem which iswithin the polygonal sleeve being polygonal in order that in itsrotation it willscrew or-unscrew the valve seat' into or from thechamber, combined with a rod which unites the piston with the valve inthe shell, and serves for turning the same, substantially as, and forthe purpose specified.

In a water closet apparatus, flushing mechanism including a pipe, awater supply in communication with one end thereof, a valve stem, anupwardly closing valve mounted thereon and controlling said watersupply, a bushing furnishing a seat for said valve and threaded in saidpipe, a bowl and a reservoir, 21 second valve on said stem for governingthe bowl connection, and means on said stem and for engagement with saidbushing to unscrew the latter.
